Students will explore how beaver dams shape the land through interacting with the teacher in a live video lesson led by PowerPoints and video clips as well as by interacting with each other through discussion questions. They will then individually work to engineer a model of a beaver dam to see how effective they can be at slowing the flow of water. These are very easy to find materials (sticks, rocks, and clay) and students love the hands-on experience they get from this lesson. The beginning of the class starts with a fun, engagement activity called Zoom-In, where we will analyze a set of pictures of the world's largest beaver dam ever found that is actually located in Canada, students will be guided through this using discussion and questioning. This will set the stage for their learning. After this, they will develop their plan and design for engineering their own beaver dam. These will be shared with the class by showing their technical drawings on the screens. After that, they will work with the supplies and engineer their own version of a beaver dam to see how well it works to slow the flow of water. They can build live on the screen so that others can see their work. Once they have finished their design, they will test it using a protocol of the same amount and method so that everyone uses the same test procedures and will have a comparable outcome. After the initial design, students will have a chance to make any changes they want and then re-test their design. The concluding activity is a reflection of how well their designs worked and what they could do to improve them in the future.
